Abstract

The book contains an introduction to matrix analysis, and to the basic algorithms of numerical linear algebra. Further results can be found in many text books. The book of Horn and Johnson [HJ85] is an excellent reference for theoretical results about matrix analysis; see also
[Bha97]. The subject of linear algebra, and matrix analysis in particular, is treated in an original and illuminating fashion in [Lax97]. For a general introduction to the subject of numerical linear algebra we recommend the book by Trefethen and Bau [TB97]; more theoretical treatments of
the subject can be found in Demmel [Dem97], Golub and Van Loan [GL96] and in Stoer and Bulirsch [SB02]. Higham's book [Hig02] contains a wealth of information about stability and
the effect of rounding errors in numerical algorithms; it is this source that we used for almost all theorems we state concerning backward error analysis. The book of Saad [Saa97] covers the subject of iterative methods for linear systems. The symmetric eigenvalue problem is analysed
in Parlett [Par80].
